Protein Synthesis Flashcards
1
Q
Different levels of protein synthesis
A
DNA - transcription - mRNA - translation - polypeptide - folding - protein
2
Q
What is an operon
A
Cluster of genes transcribed together to give a single mRNA molecule
3
Q
Lactose and tryptophan pathways
A
Lactose - when lactose is present, the lac repressor loses its ability to bind DNA, clearing the way for RNA polymerase to bind
Tryptophan - Trp repressor binds to operator, blocking Rna ploymerase and preventing transcription
